Forget switch and break, lets play with if. And instead of asserting

if(pageid === "listing-page" || pageid === "home-page")

lets create several arrays with cases and check it with Array.prototype.includes()

var caseA = ["listing-page", "home-page"];
var caseB = ["details-page", "case04", "case05"];

if(caseA.includes(pageid)) {
    alert("hello");
}
else if (caseB.includes(pageid)) {
    alert("goodbye");
}
else {
    alert("there is no else case");
}

We can use regex as: import re if re.match('[0-9]*.?[0-9]+', <your_string>): print("Its a float/int") else: print("Its something alien") let me explain the regex in english,

• * -> 0 or more occurence
• + -> 1 or more occurence
• ? -> 0/1 occurence

now, lets convert

• '[0-9]* -> let there be 0 or more occurence of digits in between 0-9
• \.? -> followed by a 0 or one '.'(if you need to check if it can be int/float else we can also use instead of ?, use {1})
• [0-9]+ -> followed by 0 or more occurence of digits in between 0-9

Modern HTML5 Techniques for changing classes

Modern browsers have added classList which provides methods to make it easier to manipulate classes without needing a library:

document.getElementById("MyElement").classList.add('MyClass');

document.getElementById("MyElement").classList.remove('MyClass');

if ( document.getElementById("MyElement").classList.contains('MyClass') )

document.getElementById("MyElement").classList.toggle('MyClass');

Unfortunately, these do not work in Internet Explorer prior to v10, though there is a shim to add support for it to IE8 and IE9, available from this page. It is, though, getting more and more supported.

Simple cross-browser solution

The standard JavaScript way to select an element is using document.getElementById("Id"), which is what the following examples use - you can of course obtain elements in other ways, and in the right situation may simply use this instead - however, going into detail on this is beyond the scope of the answer.

To change all classes for an element:

To replace all existing classes with one or more new classes, set the className attribute:

document.getElementById("MyElement").className = "MyClass";

(You can use a space-delimited list to apply multiple classes.)

To add an additional class to an element:

To add a class to an element, without removing/affecting existing values, append a space and the new classname, like so:

document.getElementById("MyElement").className += " MyClass";

To remove a class from an element:

To remove a single class to an element, without affecting other potential classes, a simple regex replace is required:

document.getElementById("MyElement").className =
   document.getElementById("MyElement").className.replace
      ( /(?:^|\s)MyClass(?!\S)/g , '' )
/* Code wrapped for readability - above is all one statement */

An explanation of this regex is as follows:

(?:^|\s) # Match the start of the string or any single whitespace character

MyClass  # The literal text for the classname to remove

(?!\S)   # Negative lookahead to verify the above is the whole classname
         # Ensures there is no non-space character following
         # (i.e. must be the end of the string or space)

The g flag tells the replace to repeat as required, in case the class name has been added multiple times.

To check if a class is already applied to an element:

The same regex used above for removing a class can also be used as a check as to whether a particular class exists:

if ( document.getElementById("MyElement").className.match(/(?:^|\s)MyClass(?!\S)/) )

Whilst it is possible to write JavaScript directly inside the HTML event attributes (such as onclick="this.className+=' MyClass'") this is not recommended behaviour. Especially on larger applications, more maintainable code is achieved by separating HTML markup from JavaScript interaction logic.

The first step to achieving this is by creating a function, and calling the function in the onclick attribute, for example:

<script type="text/javascript">
    function changeClass(){
        // Code examples from above
    }
</script>
...
<button onclick="changeClass()">My Button</button>

_{(It is not required to have this code in script tags, this is simply for the brevity of example, and including the JavaScript in a distinct file may be more appropriate.)}

The second step is to move the onclick event out of the HTML and into JavaScript, for example using addEventListener

<script type="text/javascript">
    function changeClass(){
        // Code examples from above
    }

    window.onload = function(){
        document.getElementById("MyElement").addEventListener( 'click', changeClass);
    }
</script>
...
<button id="MyElement">My Button</button>

(Note that the window.onload part is required so that the contents of that function are executed after the HTML has finished loading - without this, the MyElement might not exist when the JavaScript code is called, so that line would fail.)

JavaScript Frameworks and Libraries

The above code is all in standard JavaScript, however, it is common practice to use either a framework or a library to simplify common tasks, as well as benefit from fixed bugs and edge cases that you might not think of when writing your code.

Whilst some people consider it overkill to add a ~50  KB framework for simply changing a class, if you are doing any substantial amount of JavaScript work or anything that might have unusual cross-browser behavior, it is well worth considering.

(Very roughly, a library is a set of tools designed for a specific task, whilst a framework generally contains multiple libraries and performs a complete set of duties.)

The examples above have been reproduced below using jQuery, probably the most commonly used JavaScript library (though there are others worth investigating too).

(Note that $ here is the jQuery object.)

Changing Classes with jQuery:

$('#MyElement').addClass('MyClass');

$('#MyElement').removeClass('MyClass');

if ( $('#MyElement').hasClass('MyClass') )

In addition, jQuery provides a shortcut for adding a class if it doesn't apply, or removing a class that does:

$('#MyElement').toggleClass('MyClass');

$('#MyElement').click(changeClass);

or, without needing an id:

$(':button:contains(My Button)').click(changeClass);

Had the same issue.

I find out that react-scrips add "strict": true to tsconfig.json.

After I removed it everything works great.

Edit

Need to warn that changing this property means that you:

not being warned about potential run-time errors anymore.

as been pointed out by PaulG in comments! Thank you :)

Use "strict": false only if you fully understand what it affects!

Try with this:

It will provide you all user queries. Till spid 50,it's all are sql server internal process sessions. But, if you want you can remove where clause:

select
r.session_id,
r.start_time,
s.login_name,
c.client_net_address,
s.host_name,
s.program_name,
st.text
from sys.dm_exec_requests r
inner join sys.dm_exec_sessions s
on r.session_id = s.session_id
left join sys.dm_exec_connections c
on r.session_id = c.session_id
outer apply sys.dm_exec_sql_text(r.sql_handle) st where r.session_id  > 50

If you're running a jar file with java -jar, the -classpath argument is ignored. You need to set the classpath in the manifest file of your jar, like so:

Class-Path: jar1-name jar2-name directory-name/jar3-name

See the Java tutorials: Adding Classes to the JAR File's Classpath.

Edit: I see you already tried setting the class path in the manifest, but are you sure you used the correct syntax? If you skip the ':' after "Class-Path" like you showed, it would not work.

In the accepted answer the ConcurrentBag is not required. Here's an implementation without it:

var tasks = myCollection.Select(GetData).ToList();
await Task.WhenAll(tasks);
var results = tasks.Select(t => t.Result);

Any of the "// some pre stuff" and "// some post stuff" can go into the GetData implementation (or another method that calls GetData)

Aside from being shorter, there's no use of an "async void" lambda, which is an anti pattern.

After you installed MySQL-community-server 5.7 from fresh on linux, you will need to find the temporary password from /var/log/mysqld.log to login as root.

1. grep 'temporary password' /var/log/mysqld.log
2. Run mysql_secure_installation to change new password

If you are like me using ubuntu 10.10 & cant find the lastest version which is now

• ruby1.9.3

this is where you can get it http://www.ubuntuupdates.org/package/brightbox_ruby_ng_experimental/maverick/main/base/ruby1.9.3

& remember that it wont alter you old version of ruby

Be careful with this. There are a number of different 'contexts' within an HTML document: Inside an element, quoted attribute value, unquoted attribute value, URL attribute, javascript, CSS, etc... You'll need to use a different encoding method for each of these to prevent Cross-Site Scripting (XSS). Check the OWASP XSS Prevention Cheat Sheet for details on each of these contexts. You can find escaping methods for each of these contexts in the OWASP ESAPI library -- https://github.com/ESAPI/esapi-java-legacy.

Try This Method

For Java :

EditText yourEditText = (EditText) findViewById(R.id.yourEditText);
yourEditText.setFilters(new InputFilter[] {
new InputFilter() {
    @Override
    public CharSequence filter(CharSequence cs, int start,
                int end, Spanned spanned, int dStart, int dEnd) {
        // TODO Auto-generated method stub
        if(cs.equals("")){ // for backspace
             return cs;
        }
        if(cs.toString().matches("[a-zA-Z ]+")){
             return cs;
        }
        return "";
    }
}});

For Kotlin :

 val yourEditText = findViewById<View>(android.R.id.yourEditText) as EditText
    val reges = Regex("^[0-9a-zA-Z ]+$")
    //this will allow user to only write letter and white space
    yourEditText.filters = arrayOf<InputFilter>(
        object : InputFilter {
            override fun filter(
                cs: CharSequence, start: Int,
                end: Int, spanned: Spanned?, dStart: Int, dEnd: Int,
            ): CharSequence? {
                if (cs == "") { // for backspace
                    return cs
                }
                return if (cs.toString().matches(reges)) {
                    cs
                } else ""
            }
        }
    )

Manage multiple GitHub accounts on one Windows machine (HTTPS)

Let's say you previously use git on your machine and configure git global config file. To check it open the terminal and :

git config --global -e

It opens your editor, and you may see something like this:

[user]
    email = [email protected]
    name = Your_Name
...

And this is great because you can push your code to GitHub account without entering credentials every time. But what if it needs to push to repo from another account? In this case, git will reject with 403 err, and you must change your global git credentials. To make this comfortable lat set storing a repo name in a credential manager:

git config --global credential.github.com.useHttpPath true

to check it open config one more time git config --global -e you will see new config lines

[credential]
    useHttpPath = true
...

The is it. Now when you first time push to any account you will see a pop-up Screenshot_1

Enter specific for this repo account credentials, and this will "bind" this account for the repo. And so in your machine, you can specify as many accounts/repos as you want.

For a more expanded explanation you can see this cool video that I found on youtube: https://youtu.be/2MGGJtTH0bQ

for i in range(0, 101):
if i != 50:
    do sth
else:
    pass

You can simulate this problem with a syntax mistake, however, %matplotlib inline won't resolve the issue.

First an example of the right way to create a plot. Everything works as expected with the imports and magic that eNord9 supplied.

df_randNumbers1 = pd.DataFrame(np.random.randint(0,100,size=(100, 6)), columns=list('ABCDEF'))

df_randNumbers1.ix[:,["A","B"]].plot.kde()

However, by leaving the () off the end of the plot type you receive a somewhat ambiguous non-error.

Erronious code:

df_randNumbers1.ix[:,["A","B"]].plot.kde

Example error:

<bound method FramePlotMethods.kde of <pandas.tools.plotting.FramePlotMethods object at 0x000001DDAF029588>>

Other than this one line message, there is no stack trace or other obvious reason to think you made a syntax error. The plot doesn't print.

If there are multiple commits, you can use git rebase -i to squash two commits into one.

If there are only two commits you want to merge, and they are the "most recent two", the following commands can be used to combine the two commits into one:

git reset --soft "HEAD^"
git commit --amend

A return in the middle of the method is not necessarily bad. It might be better to return immediately if it makes the intent of the code clearer. For example:

double getPayAmount() {
    double result;
    if (_isDead) result = deadAmount();
    else {
        if (_isSeparated) result = separatedAmount();
        else {
            if (_isRetired) result = retiredAmount();
            else result = normalPayAmount();
        };
    }
     return result;
};

In this case, if _isDead is true, we can immediately get out of the method. It might be better to structure it this way instead:

double getPayAmount() {
    if (_isDead)      return deadAmount();
    if (_isSeparated) return separatedAmount();
    if (_isRetired)   return retiredAmount();

    return normalPayAmount();
};   

I've picked this code from the refactoring catalog. This specific refactoring is called: Replace Nested Conditional with Guard Clauses.

This can be caused by SELinux. If you don't want to disable SELinux completely, you need to set the db directory fcontext to httpd_sys_rw_content_t.

semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/railsapp/db(/.*)?"
restorecon -v /var/www/railsapp/db

Eclipse >> project explorer >> servers >> server.xml >> tag >> remove duplicate tag of your project

Solution without using extra ArrayList or combination of add() and remove() methods. Both can have negative impact if you have to reverse a huge list.

 public ArrayList<Object> reverse(ArrayList<Object> list) {

   for (int i = 0; i < list.size() / 2; i++) {
     Object temp = list.get(i);
     list.set(i, list.get(list.size() - i - 1));
     list.set(list.size() - i - 1, temp);
   }

   return list;
 }

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

A list is unhashable because its contents can change over its lifetime. You can update an item contained in the list at any time.

A list doesn't use a hash for indexing, so it isn't restricted to hashable items.

add this function to your global.asax

protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{
    string cookieName = FormsAuthentication.FormsCookieName;
    HttpCookie authCookie = Context.Request.Cookies[cookieName];

    if (authCookie == null)
    {
        return;
    }
    FormsAuthenticationTicket authTicket = null;
    try
    {
        authTicket = FormsAuthentication.Decrypt(authCookie.Value);
    }
    catch
    {
        return;
    }
    if (authTicket == null)
    {
        return;
    }
    string[] roles = authTicket.UserData.Split(new char[] { '|' });
    FormsIdentity id = new FormsIdentity(authTicket);
    GenericPrincipal principal = new GenericPrincipal(id, roles);

    Context.User = principal;
}

then you can use HttpContext.Current.User.Identity.Name to get username. hope it helps

It's not just Visual Studio... It'd be any tools that read the files, compilers, linkers, etc. that would have to be able to handle it.

In general (for software development) we accept the multiplatform line ending issue, but let the version control software deal with it.

If you have custom image selector for checkbox or radiobutton you must set same button and background property such as this:

            <CheckBox
                android:id="@+id/filter_checkbox_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:button="@drawable/selector_checkbox_filter"
                android:background="@drawable/selector_checkbox_filter" />

You can control size of checkbox or radio button padding with background property.

Write-Error is for non-terminating errors and throw is for terminating errors

The Write-Error cmdlet declares a non-terminating error. By default, errors are sent in the error stream to the host program to be displayed, along with output.

Non-terminating errors write an error to the error stream, but they do not stop command processing. If a non-terminating error is declared on one item in a collection of input items, the command continues to process the other items in the collection.

To declare a terminating error, use the Throw keyword. For more information, see about_Throw (http://go.microsoft.com/fwlink/?LinkID=145153).

You're close. You can strip the whitespace by using the replace method like this:

$answer.replace(' ','')

There needs to be no space or characters between the second set of quotes in the replace method (replacing the whitespace with nothing).

plt.axis('off')
plt.savefig(file_path, bbox_inches="tight", pad_inches = 0)

plt.savefig has those options in itself, just need to set axes off before

UnxUtils is the one I use, works perfectly for me...

If you need an instance of HashMap, the best way is:

fileParameters = new HashMap<String,String>();

Since Map is an interface, you need to pick some class that instantiates it if you want to create an empty instance. HashMap seems as good as any other - so just use that.

You can parse a String to a Uri by using Uri.parse() as shown below:

Uri myUri = Uri.parse("http://stackoverflow.com");

The following is an example of how you can use your newly created Uri in an implicit intent. To be viewed in a browser on the users phone.

// Creates a new Implicit Intent, passing in our Uri as the second paramater.
Intent webIntent = new Intent(Intent.ACTION_VIEW, myUri);

// Checks to see if there is an Activity capable of handling the intent
if (webIntent.resolveActivity(getPackageManager()) != null){
    startActivity(webIntent);
}

NB: There is a difference between Androids URI and Uri.

Zambri's answer found here is the best.

File.open("out.txt", '<OPTION>') {|f| f.write("write your stuff here") }

where your options for <OPTION> are:

r - Read only. The file must exist.

w - Create an empty file for writing.

a - Append to a file.The file is created if it does not exist.

r+ - Open a file for update both reading and writing. The file must exist.

w+ - Create an empty file for both reading and writing.

a+ - Open a file for reading and appending. The file is created if it does not exist.

In your case, w is preferable.

I've tested this:

When I open an Excel document D:\db\tmp\test1.xlsm:

• CurDir() returns C:\Users\[username]\Documents

• ActiveWorkbook.Path returns D:\db\tmp

So CurDir() has a system default and can be changed.

ActiveWorkbook.Path does not change for the same saved Workbook.

For example, CurDir() changes when you do "File/Save As" command, and select a random directory in the File/Directory selection dialog. Then click on Cancel to skip saving. But CurDir() has already changed to the last selected directory.

This Perl one-liner shows how closely Perl is related to awk:

perl -lane 'print $F[3]' text.txt

However, the @F autosplit array starts at index $F[0] while awk fields start with $1

For Bootstrap 4
Some of the previous answers are not working for Bootstrap 4. To reduce the size of the navigation bar in this version, I suggest eliminating the padding like this.

.navbar { padding-top: 0.25rem; padding-bottom: 0.25rem; }

You could try with other styles too.
The styles I found that define the total height of the navigation bar are:

• padding-top and padding-bottom are set to 0.5rem for .navbar.
• padding-top and padding-bottom are set to 0.5rem for .navbar-text.
• besides a line-height of 1.5rem inherited from the body.

Thus, in total the navigation bar is 3.5 times the root font size.

In my case, which I was using big font sizes; I redefined the ".navbar" class in my CSS file like this:

.navbar {
  padding-top:    0.25rem; /* 0px does not look good on small screens */
  padding-bottom: 0.25rem;
  font-size: smaller;      /* Just because I am using big size font */
  line-height: 1em;
}

Final comment, avoid using absolute values when playing with the previous styles. Use the units rem or em instead.

expr(1) has a substr subcommand:

expr substr <string> <start-index> <length>

This may be useful if you don't have bash (perhaps embedded Linux) and you don't want the extra "echo" process you need to use cut(1).

In JQuery you can call

$("form:first").trigger("submit")

Don't know if that is much better. I think form.submit(); is pretty universal.

Header rows in data are a perpetual headache in Hive. Short of modifying the Hive source, I believe you can't get away without an intermediate step. (Edit: This is no longer true, see update below)

Unfortunately, that answers you question. I'll throw in some ideas for the intermediate step for completeness.

You can get away without an extra step in your data load if you are willing to filter out the header row on every query that touches the table. Unfortunately this adds an extra set just about everywhere else. And you will have to get clever/messy when the header row violates your schema. If you go with this approach, you might consider writing a custom SerDe that makes this row easier to filter. Unfortunately, SerDe's cannot remove the row entirely (or that might form a possible solution), they must return something like null. I've never seen this approach taken in practice to deal with header rows since it makes reading a pain, and reading tends to be much more common than writing. It might have a place if you are dealing with one-of tables or if the header row is just one row among many malformed rows.

You could do this filtering once with variations on deleting that first row in data load. A WHERE clause in an INSERT statement would do it. You could use utilities like sed to get rid of it. I've seen both approaches taken. There are trade-offs between which approach you take and neither is the one true way to deal with header rows. Unfortunately, both these approaches take time and require temporary duplication of the data. If you absolutely need the header row for another application, the duplication would be permanent.

Update:

From Hive v0.13.0, you can use skip.header.line.count. You could also specify the same while creating the table. For example:

create external table testtable (name string, message string)
row format delimited 
fields terminated by '\t' 
lines terminated by '\n' 
location '/testtable'
tblproperties ("skip.header.line.count"="1");

hive> show partitions table_name;

You can use inline styling to limit the height:

<img src="" class="img-responsive" alt="" style="max-height: 400px;">

In postgresql you can use regular expressions in WHERE clause. Check http://www.postgresql.org/docs/8.4/static/functions-matching.html

MySQL has something simmilar: http://dev.mysql.com/doc/refman/5.5/en/regexp.html

The way that Magento themes handle actual url's is as such (in view partials - phtml files):

echo $this->getSkinUrl('images/logo.png');

If you need the actual base path on disk to the image directory use:

echo Mage::getBaseDir('skin');

Some more base directory types are available in this great blog post:

If getFiles() returns a java.util.Collection, !getFiles().isEmpty() && size<5 can be OK.

On the other hand, unless you encapsulate the container which provides method such as boolean sizeBetween(int min, int max).

I tried above solution, but the following code help me to close this issue.

if (18 < Build.VERSION.SDK_INT ){
    //18 = JellyBean MR2, KITKAT=19
    mWeb.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
}

I started with johncarls solution, but needed to adjust it to get exactly what I needed. Mainly, I needed it to rotate clockwise when the angle increased. I also needed 0 degrees to point NORTH. His solution got me close, but I decided to post my solution as well in case it helps anyone else.

I've added some additional comments to help explain my understanding of the function in case you need to make simple modifications.

/**
 * Calculates the angle from centerPt to targetPt in degrees.
 * The return should range from [0,360), rotating CLOCKWISE, 
 * 0 and 360 degrees represents NORTH,
 * 90 degrees represents EAST, etc...
 *
 * Assumes all points are in the same coordinate space.  If they are not, 
 * you will need to call SwingUtilities.convertPointToScreen or equivalent 
 * on all arguments before passing them  to this function.
 *
 * @param centerPt   Point we are rotating around.
 * @param targetPt   Point we want to calcuate the angle to.  
 * @return angle in degrees.  This is the angle from centerPt to targetPt.
 */
public static double calcRotationAngleInDegrees(Point centerPt, Point targetPt)
{
    // calculate the angle theta from the deltaY and deltaX values
    // (atan2 returns radians values from [-PI,PI])
    // 0 currently points EAST.  
    // NOTE: By preserving Y and X param order to atan2,  we are expecting 
    // a CLOCKWISE angle direction.  
    double theta = Math.atan2(targetPt.y - centerPt.y, targetPt.x - centerPt.x);

    // rotate the theta angle clockwise by 90 degrees 
    // (this makes 0 point NORTH)
    // NOTE: adding to an angle rotates it clockwise.  
    // subtracting would rotate it counter-clockwise
    theta += Math.PI/2.0;

    // convert from radians to degrees
    // this will give you an angle from [0->270],[-180,0]
    double angle = Math.toDegrees(theta);

    // convert to positive range [0-360)
    // since we want to prevent negative angles, adjust them now.
    // we can assume that atan2 will not return a negative value
    // greater than one partial rotation
    if (angle < 0) {
        angle += 360;
    }

    return angle;
}

You can add this code:

function parseBool(str) {

  if (str.length == null) {
    return str == 1 ? true : false;
  } else {
    return str == "true" ? true : false;
  }

}

Works like this:

parseBool(1) //true
parseBool(0) //false
parseBool("true") //true
parseBool("false") //false

For the record, none of the answers above helped except for one. To summarize, you can do the backup operation using --files-from= by using either:

 rsync -aSvuc `cat rsync-src-files` /mnt/d/rsync_test/

OR

 rsync -aSvuc --recursive --files-from=rsync-src-files . /mnt/d/rsync_test/

The former command is self explanatory, beside the content of the file rsync-src-files which I will elaborate down below. Now, if you want to use the latter version, you need to keep in mind the following four remarks:

1. Notice one needs to specify both --files-from and the source directory
2. One needs to explicitely specify --recursive.
3. The file rsync-src-files is a user created file and it was placed within the src directory for this test
4. The rsyn-src-files contain the files and folders to copy and they are taken relative to the source directory. IMPORTANT: Make sure there is not trailing spaces or blank lines in the file. In the example below, there are only two lines, not three (Figure it out by chance). Content of rsynch-src-files is:

folderName1
folderName2

yes, static block is used for initialize the code and it will load at the time JVM start for execution.

static block is used in previous versions of java but in latest version it doesn't work.

Least amount of markup possible (you only need one span):

<p>This text is left. <span>This text is right.</span></p>

How you want to achieve the left/right styles is up to you, but I would recommend an external style on an ID or a class.

The full HTML:

<p class="split-para">This text is left. <span>This text is right.</span></p>

And the CSS:

.split-para      { display:block;margin:10px;}
.split-para span { display:block;float:right;width:50%;margin-left:10px;}

The shortest in terms of lines of code i can think of is for the first question.

>>> import numpy as np
>>> p = np.array([[1,2],[3,4]])

>>> p = np.append(p, [[5,6]], 0)
>>> p = np.append(p, [[7],[8],[9]],1)

>>> p
array([[1, 2, 7],
   [3, 4, 8],
   [5, 6, 9]])

And the for the second question

    p = np.array(range(20))
>>> p.shape = (4,5)
>>> p
array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]])
>>> n = 2
>>> p = np.append(p[:n],p[n+1:],0)
>>> p = np.append(p[...,:n],p[...,n+1:],1)
>>> p
array([[ 0,  1,  3,  4],
       [ 5,  6,  8,  9],
       [15, 16, 18, 19]])

To avoid the focus advancing to the next editable field (if you have one) you might want to ignore the key-down events, but handle key-up events. I also prefer to filter first on the keyCode, assuming that it would be marginally more efficient. By the way, remember that returning true means that you have handled the event, so no other listener will. Anyway, here is my version.

ETFind.setOnKeyListener(new OnKeyListener()
{
    public boolean onKey(View v, int keyCode, KeyEvent event)
    {
        if (keyCode ==  KeyEvent.KEYCODE_DPAD_CENTER
        || keyCode ==  KeyEvent.KEYCODE_ENTER) {

            if (event.getAction() == KeyEvent.ACTION_DOWN) {
                // do nothing yet
            } else if (event.getAction() == KeyEvent.ACTION_UP) {
                        findForward();      
            } // is there any other option here?...

            // Regardless of what we did above,
            // we do not want to propagate the Enter key up
            // since it was our task to handle it.
            return true;

        } else {
            // it is not an Enter key - let others handle the event
            return false;
        }
    }

});

While you can have a default page in the MVC project, the more conventional implementation for a default view would be to use a default controller, implememented in the global.asax, through the 'RegisterRoutes(...)' method. For instance if you wanted your Public\Home controller to be your default route/view, the code would be:

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Public", action = "Home", id = UrlParameter.Optional } // Parameter defaults
        );

    }

For this to be functional, you are required to have have a set Start Page in the project.

Use:

SELECT t1.Notes, 
       t2.Name
  FROM Table1 t1
  JOIN Table2 t2 ON t1.Notes LIKE CONCAT('%', t2.Name ,'%')

Below is corrected Snippet of runThread Function.

private void runThread() {

    new Thread() {
        public void run() {
            while (i++ < 1000) {
                try {
                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            btn.setText("#" + i);
                        }
                    });
                    Thread.sleep(300);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }.start();
}

Thread

When you start an app, a process is created to execute the code. To efficiently use computing resource, threads can be started within the process so that multiple tasks can be executed at the time. So threads allow you to build efficient apps by utilizing cpu efficiently without idle time.

In Android, all components execute on a single called main thread. Android system queue tasks and execute them one by one on the main thread. When long running tasks are executed, app become unresponsive.

To prevent this, you can create worker threads and run background or long running tasks.

Handler

Since android uses single thread model, UI components are created non-thread safe meaning only the thread it created should access them that means UI component should be updated on main thread only. As UI component run on the main thread, tasks which run on worker threads can not modify UI components. This is where Handler comes into picture. Handler with the help of Looper can connect to new thread or existing thread and run code it contains on the connected thread.

Handler makes it possible for inter thread communication. Using Handler, background thread can send results to it and the handler which is connected to main thread can update the UI components on the main thread.

AsyncTask

AsyncTask provided by android uses both thread and handler to make running simple tasks in the background and updating results from background thread to main thread easy.

Please see android thread, handler, asynctask and thread pools for examples.

One line code to detect the browser.

If the browser is IE or Edge, It will return true;

let isIE = /edge|msie\s|trident\//i.test(window.navigator.userAgent)

The function that I use to find the length of the string is length, used as follows:

SELECT * FROM table ORDER BY length(column);

My 2 cents:

If you are concatenating a significant amount of strings, you should be using the StringBuilder instead. IMO it's cleaner, and significantly faster.

You can use the native JS slice method:

<div v-for="item in shoppingItems.slice(0,10)">

The slice() method returns the selected elements in an array, as a new array object.

Based on tip in the migration guide: https://vuejs.org/v2/guide/migration.html#Replacing-the-limitBy-Filter

Objects created by new must be eventually deleted lest they leak. The destructor won't be called, memory won't be freed, the whole bit. Since C++ has no garbage collection, it's a problem.

Objects created by value (i. e. on stack) automatically die when they go out of scope. The destructor call is inserted by the compiler, and the memory is auto-freed upon function return.

Smart pointers like unique_ptr, shared_ptr solve the dangling reference problem, but they require coding discipline and have other potential issues (copyability, reference loops, etc.).

Also, in heavily multithreaded scenarios, new is a point of contention between threads; there can be a performance impact for overusing new. Stack object creation is by definition thread-local, since each thread has its own stack.

The downside of value objects is that they die once the host function returns - you cannot pass a reference to those back to the caller, only by copying, returning or moving by value.

We needed to serialise an arbitrary object hierarchy, where the root or any of the nested properties in the hierarchy could be instances of Error.

Our solution was to use the replacer param of JSON.stringify(), e.g.:

function jsonFriendlyErrorReplacer(key, value) {_x000D_
  if (value instanceof Error) {_x000D_
    return {_x000D_
      // Pull all enumerable properties, supporting properties on custom Errors_x000D_
      ...value,_x000D_
      // Explicitly pull Error's non-enumerable properties_x000D_
      name: value.name,_x000D_
      message: value.message,_x000D_
      stack: value.stack,_x000D_
    }_x000D_
  }_x000D_
_x000D_
  return value_x000D_
}_x000D_
_x000D_
let obj = {_x000D_
    error: new Error('nested error message')_x000D_
}_x000D_
_x000D_
console.log('Result WITHOUT custom replacer:', JSON.stringify(obj))_x000D_
console.log('Result WITH custom replacer:', JSON.stringify(obj, jsonFriendlyErrorReplacer))

Changing your lists to numpy arrays will do the job!!

As you've indicated, you can't output NULL in an excel formula. I think this has to do with the fact that the formula itself causes the cell to not be able to be NULL. "" is the next best thing, but sometimes it's useful to use 0.

--EDIT--

Based on your comment, you might want to check out this link. http://peltiertech.com/WordPress/mind-the-gap-charting-empty-cells/

It goes in depth on the graphing issues and what the various values represent, and how to manipulate their output on a chart.

I'm not familiar with VSTO I'm afraid. So I won't be much help there. But if you are really placing formulas in the cell, then there really is no way. ISBLANK() only tests to see if a cell is blank or not, it doesn't have a way to make it blank. It's possible to write code in VBA (and VSTO I imagine) that would run on a worksheet_change event and update the various values instead of using formulas. But that would be cumbersome and performance would take a hit.

What I do is have a static class with the following code in my project:

    #region Dataset -> Immediate Window
public static void printTbl(DataSet myDataset)
{
    printTbl(myDataset.Tables[0]);
}
public static void printTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        Debug.Write(mytable.Columns[i].ToString() + " | ");
    }
    Debug.Write(Environment.NewLine + "=======" + Environment.NewLine);
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            Debug.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        Debug.Write(Environment.NewLine);
    }
}
public static void ResponsePrintTbl(DataTable mytable)
{
    for (int i = 0; i < mytable.Columns.Count; i++)
    {
        HttpContext.Current.Response.Write(mytable.Columns[i].ToString() + " | ");
    }
    HttpContext.Current.Response.Write("<BR>" + "=======" + "<BR>");
    for (int rrr = 0; rrr < mytable.Rows.Count; rrr++)
    {
        for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
        {
            HttpContext.Current.Response.Write(mytable.Rows[rrr][ccc] + " | ");
        }
        HttpContext.Current.Response.Write("<BR>");
    }
}

public static void printTblRow(DataSet myDataset, int RowNum)
{
    printTblRow(myDataset.Tables[0], RowNum);
}
public static void printTblRow(DataTable mytable, int RowNum)
{
    for (int ccc = 0; ccc < mytable.Columns.Count; ccc++)
    {
        Debug.Write(mytable.Columns[ccc].ToString() + " : ");
        Debug.Write(mytable.Rows[RowNum][ccc]);
        Debug.Write(Environment.NewLine);
    }
}

I then I will call one of the above functions in the immediate window and the results will appear there as well. For example if I want to see the contents of a variable 'myDataset' I will call printTbl(myDataset). After hitting enter, the results will be printed to the immediate window

I am sure we have a lot of good answers here. But, I just thought of adding the way I have used enumerated types

package main

import "fmt"

type Enum interface {
    name() string
    ordinal() int
    values() *[]string
}

type GenderType uint

const (
    MALE = iota
    FEMALE
)

var genderTypeStrings = []string{
    "MALE",
    "FEMALE",
}

func (gt GenderType) name() string {
    return genderTypeStrings[gt]
}

func (gt GenderType) ordinal() int {
    return int(gt)
}

func (gt GenderType) values() *[]string {
    return &genderTypeStrings
}

func main() {
    var ds GenderType = MALE
    fmt.Printf("The Gender is %s\n", ds.name())
}

This is by far one of the idiomatic ways we could create Enumerated types and use in Go.

Edit:

Adding another way of using constants to enumerate

package main

import (
    "fmt"
)

const (
    // UNSPECIFIED logs nothing
    UNSPECIFIED Level = iota // 0 :
    // TRACE logs everything
    TRACE // 1
    // INFO logs Info, Warnings and Errors
    INFO // 2
    // WARNING logs Warning and Errors
    WARNING // 3
    // ERROR just logs Errors
    ERROR // 4
)

// Level holds the log level.
type Level int

func SetLogLevel(level Level) {
    switch level {
    case TRACE:
        fmt.Println("trace")
        return

    case INFO:
        fmt.Println("info")
        return

    case WARNING:
        fmt.Println("warning")
        return
    case ERROR:
        fmt.Println("error")
        return

    default:
        fmt.Println("default")
        return

    }
}

func main() {

    SetLogLevel(INFO)

}

There is a difference in performance.

Simply put HS256 is about 1 order of magnitude faster than RS256 for verification but about 2 orders of magnitude faster than RS256 for issuing (signing).

 640,251  91,464.3 ops/s
  86,123  12,303.3 ops/s (RS256 verify)
   7,046   1,006.5 ops/s (RS256 sign)

Don't get hung up on the actual numbers, just think of them with respect of each other.

No need to rely on Generating a Personal Access Token and then trying and use Personal Access Token in the place of your password.

Quick fix is to set your remote URL to point to ssh not https.

Do this git remote set-url origin [email protected]:username/repository

//Page load starts here

var json = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(new

});

var json2 = "{\"api_key\":\"my key\",\"action\":\"categories\",\"store_id\":\"my store\",\"user\" : {\"id\" : 12345,\"screen_name\" : \"twitpicuser\"}}";
var list = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<FooBar>(json);
var list2 = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<FooBar>(json2);

string a = list2.action;
var b = list2.user;
string c = b.screen_name;

//Page load ends here

public class FooBar

    public string api_key { get; set; }
    public string action { get; set; }
    public string store_id { get; set; }

public class User

What type of authentication do you use? Send the credentials using the properties Ben said before and setup a cookie handler. You already allow redirection, check your webserver if any redirection occurs (NTLM auth does for sure). If there is a redirection you need to store the session which is mostly stored in a session cookie.

var tests = new[] {"000000001000", "000000001005", "000000331150"};
foreach (var test in tests)
{
    Console.WriteLine("{0} <=> {1:f2}", test, Convert.ToDecimal(test) / 100);
}

Since you didn't ask for the currency symbol, I've used "f2" instead of "C"

Using Git for version control

Visual studio code have Integrated Git Support.

• Steps to use git.

Install Git : https://git-scm.com/downloads

1) Initialize your repository

Navigate to directory where you want to initialize Git

Use git init command This will create a empty .git repository

2) Stage the changes

Staging is process of making Git to track our newly added files. For example add a file and type git status. You will find the status that untracked file. So to stage the changes use git add filename. If now type git status, you will find that new file added for tracking.

You can also unstage files. Use git reset

3) Commit Changes

Commiting is the process of recording your changes to repository. To commit the statges changes, you need to add a comment that explains the changes you made since your previous commit.

Use git commit -m message string

We can also commit the multiple files of same type using command git add '*.txt'. This command will commit all files with txt extension.

4) Follow changes

The aim of using version control is to keep all versions of each and every file in our project, Compare the the current version with last commit and keep the log of all changes.

Use git log to see the log of all changes.

Visual studio code’s integrated git support help us to compare the code by double clicking on the file OR Use git diff HEAD

You can also undo file changes at the last commit. Use git checkout -- file_name

5) Create remote repositories

Till now we have created a local repository. But in order to push it to remote server. We need to add a remote repository in server.

Use git remote add origin server_git_url

Then push it to server repository

Use git push -u origin master

Let assume some time has passed. We have invited other people to our project who have pulled our changes, made their own commits, and pushed them.

So to get the changes from our team members, we need to pull the repository.

Use git pull origin master

6) Create Branches

Lets think that you are working on a feature or a bug. Better you can create a copy of your code(Branch) and make separate commits to. When you have done, merge this branch back to their master branch.

Use git branch branch_name

Now you have two local branches i.e master and XXX(new branch). You can switch branches using git checkout master OR git checkout new_branch_name

Commiting branch changes using git commit -m message

Switch back to master using git checkout master

Now we need to merge changes from new branch into our master Use git merge branch_name

Good! You just accomplished your bugfix Or feature development and merge. Now you don’t need the new branch anymore. So delete it using git branch -d branch_name

Now we are in the last step to push everything to remote repository using git push

Hope this will help you

You could simply use

return

which does exactly the same as

return None

Your function will also return None if execution reaches the end of the function body without hitting a return statement. Returning nothing is the same as returning None in Python.

Ok, If all you need to do is associate the already existing image file path with the ImageField, then this solution may be helpfull:

from django.core.files.base import ContentFile

with open('/path/to/already/existing/file') as f:
  data = f.read()

# obj.image is the ImageField
obj.image.save('imgfilename.jpg', ContentFile(data))

Well, if be earnest, the already existing image file will not be associated with the ImageField, but the copy of this file will be created in upload_to dir as 'imgfilename.jpg' and will be associated with the ImageField.

All it takes is a bit of XAML...

<Window x:Class="WCSamples.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Window.CommandBindings>
        <CommandBinding Command="ApplicationCommands.Close"
                        Executed="CloseCommandHandler"/>
    </Window.CommandBindings>
    <StackPanel Name="MainStackPanel">
        <Button Command="ApplicationCommands.Close" 
                Content="Close Window" />
    </StackPanel>
</Window>

And a bit of C#...

{
    this.Close();
}

as conditional formatting. Highlight column A. Choose conditional formatting by forumula. Enter the formula (above) - this finds values in col B that are also in A. Choose a format (I like to use FILL and a bold color).

To find all of those values, highlight col A. Data > Filter and choose Filter by color.

In my memory, excel (versions >= 2007) limits the power 2 of 20: 1.048.576 lines.

Csv is over to this boundary, like ordinary text file. So you will be care of the transfer between two formats.

The bash script solution:

if ! xset q &>/dev/null; then
    echo "No X server at \$DISPLAY [$DISPLAY]" >&2
    exit 1
fi

Doesn't work if you login from another console (Ctrl+Alt+F?) or ssh. For me this solution works in my Archlinux:

#!/bin/sh
ps aux|grep -v grep|grep "/usr/lib/Xorg"
EXITSTATUS=$?
if [ $EXITSTATUS -eq 0 ]; then
  echo "X server running"
  exit 1
fi

You can change /usr/lib/Xorg for only Xorg or the proper command on your system.

earl's answer gives you the solution, but I thought I'd add what the problem is that's causing your IllegalStateException. You're calling group(1) without having first called a matching operation (such as find()). This isn't needed if you're just using $1 since the replaceAll() is the matching operation.

would take time to route through TeamViewer's servers (TeamViewer bypasses corporate Symmetric NATs by simply proxying traffic through their servers)

You'll find that TeamViewer rarely needs to relay traffic through their own servers. TeamViewer penetrates NAT and networks complicated by NAT using NAT traversal (I think it is UDP hole-punching, like Google's libjingle).

They do use their own servers to middle-man in order to do the handshake and connection set-up, but most of the time the relationship between client and server will be P2P (best case, when the hand-shake is successful). If NAT traversal fails, then TeamViewer will indeed relay traffic through its own servers.

I've only ever seen it do this when a client has been behind double-NAT, though.

Here is a quick start to get the gears turning...

ParkingLot is a class.

ParkingSpace is a class.

ParkingSpace has an Entrance.

Entrance has a location or more specifically, distance from Entrance.

ParkingLotSign is a class.

ParkingLot has a ParkingLotSign.

ParkingLot has a finite number of ParkingSpaces.

HandicappedParkingSpace is a subclass of ParkingSpace.

RegularParkingSpace is a subclass of ParkingSpace.

CompactParkingSpace is a subclass of ParkingSpace.

ParkingLot keeps array of ParkingSpaces, and a separate array of vacant ParkingSpaces in order of distance from its Entrance.

ParkingLotSign can be told to display "full", or "empty", or "blank/normal/partially occupied" by calling .Full(), .Empty() or .Normal()

Parker is a class.

Parker can Park().

Parker can Unpark().

Valet is a subclass of Parker that can call ParkingLot.FindVacantSpaceNearestEntrance(), which returns a ParkingSpace.

Parker has a ParkingSpace.

Parker can call ParkingSpace.Take() and ParkingSpace.Vacate().

Parker calls Entrance.Entering() and Entrance.Exiting() and ParkingSpace notifies ParkingLot when it is taken or vacated so that ParkingLot can determine if it is full or not. If it is newly full or newly empty or newly not full or empty, it should change the ParkingLotSign.Full() or ParkingLotSign.Empty() or ParkingLotSign.Normal().

HandicappedParker could be a subclass of Parker and CompactParker a subclass of Parker and RegularParker a subclass of Parker. (might be overkill, actually.)

In this solution, it is possible that Parker should be renamed to be Car.

Implementation with Guzzle library:

use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;

$httpClient = new Client();

$response = $httpClient->post(
    'https://postman-echo.com/post',
    [
        RequestOptions::BODY => 'POST raw request content',
        RequestOptions::HEADERS => [
            'Content-Type' => 'application/x-www-form-urlencoded',
        ],
    ]
);

echo(
    $response->getBody()->getContents()
);

PHP CURL extension:

$curlHandler = curl_init();

curl_setopt_array($curlHandler, [
    CURLOPT_URL => 'https://postman-echo.com/post',
    CURLOPT_RETURNTRANSFER => true,

    /**
     * Specify POST method
     */
    CURLOPT_POST => true,

    /**
     * Specify request content
     */
    CURLOPT_POSTFIELDS => 'POST raw request content',
]);

$response = curl_exec($curlHandler);

curl_close($curlHandler);

echo($response);

Source code

Bitwise operations, including bit shift, are fundamental to low-level hardware or embedded programming. If you read a specification for a device or even some binary file formats, you will see bytes, words, and dwords, broken up into non-byte aligned bitfields, which contain various values of interest. Accessing these bit-fields for reading/writing is the most common usage.

A simple real example in graphics programming is that a 16-bit pixel is represented as follows:

  bit | 15| 14| 13| 12| 11| 10| 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1  | 0 |
      |       Blue        |         Green         |       Red          |

To get at the green value you would do this:

 #define GREEN_MASK  0x7E0
 #define GREEN_OFFSET  5

 // Read green
 uint16_t green = (pixel & GREEN_MASK) >> GREEN_OFFSET;

Explanation

In order to obtain the value of green ONLY, which starts at offset 5 and ends at 10 (i.e. 6-bits long), you need to use a (bit) mask, which when applied against the entire 16-bit pixel, will yield only the bits we are interested in.

#define GREEN_MASK  0x7E0

The appropriate mask is 0x7E0 which in binary is 0000011111100000 (which is 2016 in decimal).

uint16_t green = (pixel & GREEN_MASK) ...;

To apply a mask, you use the AND operator (&).

uint16_t green = (pixel & GREEN_MASK) >> GREEN_OFFSET;

After applying the mask, you'll end up with a 16-bit number which is really just a 11-bit number since its MSB is in the 11th bit. Green is actually only 6-bits long, so we need to scale it down using a right shift (11 - 6 = 5), hence the use of 5 as offset (#define GREEN_OFFSET 5).

Also common is using bit shifts for fast multiplication and division by powers of 2:

 i <<= x;  // i *= 2^x;
 i >>= y;  // i /= 2^y;

You can also use:

$('#test').context.scrollHeight

That can be caused by unicode or other charset mismatch. Try changing charset in your browser, in of the settings the text will look OK. Then it's question of how to convert your database contents to charset you use for displaying. (Which can actually be just adding utf-8 charset statement to your output.)

The original question is "What could be the reason for this issue?" and the answer is discussed at https://github.com/kubernetes/kubernetes/issues/51835 & https://github.com/kubernetes/kubernetes/issues/65569 & see https://www.bountysource.com/issues/33241128-unable-to-remove-a-stopped-container-device-or-resource-busy

Its caused by docker mount leaking into some other namespace.

You can logon to pod host to investigate.

minikube ssh
docker container ps | grep <id>
docker container stop <id> 

To keep images from stretching in either axis inside a flex parent I have found a couple of solutions.

You can try using object-fit on the image which, e.g.

object-fit: contain;

http://jsfiddle.net/ykw3sfjd/

Or you can add flex-specfic rules which may work better in some cases.

align-self: center;
flex: 0 0 auto;

Giving the sql service account 'NT SERVICE\MSSQLSERVER' "Full Control" of the database files

If you have access to the server files/folders you can try this solution that worked for me:

SQL Server 2012 on Windows Server 2008 R2

1. Right click the database (mdf/ldf) file or folder and select "Properties".
2. Select "Security" tab and click the "Edit" button.
3. Click the "Add" button.
4. Enter the object name to select as 'NT SERVICE\MSSQLSERVER' and click "Check Names" button.
5. Select the MSSQLSERVER (RDN) and click the "OK" button twice.
6. Give this service account "Full control" to the file or folder.
7. Back in SSMS, right click the database and select "Properties".
8. Under "Options", scroll down to the "State" section and change "Database Read-Only" from "True" to "False".

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

In python functions aren't accessible magically from everywhere (like they are in say, php). They have to be declared first. So this will work:

def pyth_test (x1, x2):
    print x1 + x2

pyth_test(1, 2)

But this won't:

pyth_test(1, 2)

def pyth_test (x1, x2):
    print x1 + x2

1. Select columns A:H with A1 as the active cell.
2. Open Home ? Styles ? Conditional Formatting ? New Rule.
3. Choose Use a formula to determine which cells to format and supply one of the following formulas¹ in the Format values where this formula is true: text box.
   • To highlight the Account and Store Manager columns when one of the four dates is blank:
             =AND(LEN($A1), COLUMN()<3, COUNTBLANK($E1:$H1))
   • To highlight the Account, Store Manager and blank date columns when one of the four dates is blank:
             =AND(LEN($A1), OR(COLUMN()<3, AND(COLUMN()>4, COUNTBLANK(A1))), COUNTBLANK($E1:$H1))
4. Click [Format] and select a cell Fill.
5. Click [OK] to accept the formatting and then [OK] again to create the new rule. In both cases, the Applies to: will refer to =$A:$H.

Results should be similar to the following.

¹ _{The COUNTBLANK function was introduced with Excel 2007. It will count both true blanks and zero-length strings left by formulas (e.g. "").}

Using Bootstrap's built in .center-block class, which sets margin left and right to auto:

<iframe class="center-block" width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>

Or using the built in .text-center class, which sets text-align: center:

<div class="text-center">
  <iframe width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>
</div>

USE MyDatabase
SELECT Count(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE';

to get table counts

SELECT COUNT(*)
FROM information_schema.tables
WHERE table_schema = 'dbName';

this also works

USE databasename;
SHOW TABLES;
SELECT FOUND_ROWS();

.find(:all, where: "value LIKE product_%", params: { limit: 20, page: 1 })

Adding the following line into the form worked for me:

<%= hidden_field_tag :authenticity_token, form_authenticity_token %>

Suposed you saved a new file changes. (navbar.component.html for example)

Run:

ng status
modified:   src/app/components/shared/navbar/navbar.component.html

If you want to upload those changes for that file you must run:

git add src/app/components/shared/navbar/navbar.component.html

And then:

git commit src/app/components/shared/navbar/navbar.component.html -m "new navbar changes and fixes"

And then:

git push origin [your branch name, usually "master"]

---------------------------------------------------------------

Or if you want to upload all your changes (several/all files):

git commit -a

And them this will appear "Please enter the commit message for your changes."

• You'll see this message if you git commit without a message (-m)
• You can get out of it with two steps:
• 1.a. Type a multi-line message to move foward with the commit.
• 1.b. Leave blank to abort the commit.
• 2. Hit "esc" then type ":wq" and hit enter to save your choice. Viola!

And then:

git push

And Viola!

Generating a random string of characters is easy - just use java.util.Random and a string containing all the characters you want to be available, e.g.

public static String generateString(Random rng, String characters, int length)
{
    char[] text = new char[length];
    for (int i = 0; i < length; i++)
    {
        text[i] = characters.charAt(rng.nextInt(characters.length()));
    }
    return new String(text);
}

Now, for uniqueness you'll need to store the generated strings somewhere. How you do that will really depend on the rest of your application.

Although I have read a lot documentation about this one, I'm still confusing on how, when, and where to use it.

Make it very simple to understand:

When you have a similar situation like this:

    String strA = null;
    String strB = null;
    if (2 > 1){
        strA = "Hello World";
    }

    strB = strA.toLowerCase(); 

You might receive warning (displaying yellow line on strB = strA.toLowerCase(); ) that strA might produce a NULL value to strB. Although you know that strB is absolutely won't be null in the end, just in case, you use assert to

1. Disable the warning.

2. Throw Exception error IF worst thing happens (when you run your application).

Sometime, when you compile your code, you don't get your result and it's a bug. But the application won't crash, and you spend a very hard time to find where is causing this bug.

So, if you put assert, like this:

    assert strA != null; //Adding here
    strB = strA .toLowerCase();

you tell the compiler that strA is absolutely not a null value, it can 'peacefully' turn off the warning. IF it is NULL (worst case happens), it will stop the application and throw a bug to you to locate it.

You can use browscap-java to get browser's information.

For Example:

UserAgentParser parser = new UserAgentService().loadParser(Arrays.asList(BrowsCapField.BROWSER));
    Capabilities capabilities = parser.parse(user_agent);

    String browser = capabilities.getBrowser();

As per dart 2.6

The optional onError parameter of int.parse is deprecated. Therefore, you should use int.tryParse instead.

Note: The same applies to double.parse. Therefore, use double.tryParse instead.

  /**
   * ...
   *
   * The [onError] parameter is deprecated and will be removed.
   * Instead of `int.parse(string, onError: (string) => ...)`,
   * you should use `int.tryParse(string) ?? (...)`.
   *
   * ...
   */
  external static int parse(String source, {int radix, @deprecated int onError(String source)});

The difference is that int.tryParse returns null if the source string is invalid.

  /**
   * Parse [source] as a, possibly signed, integer literal and return its value.
   *
   * Like [parse] except that this function returns `null` where a
   * similar call to [parse] would throw a [FormatException],
   * and the [source] must still not be `null`.
   */
  external static int tryParse(String source, {int radix});

So, in your case it should look like:

// Valid source value
int parsedValue1 = int.tryParse('12345');
print(parsedValue1); // 12345

// Error handling
int parsedValue2 = int.tryParse('');
if (parsedValue2 == null) {
  print(parsedValue2); // null
  //
  // handle the error here ...
  //
}

If you're not using HTML5 this is a pretty basic JavaScript form validation.

Side note - I'd change the value to 0 on the blur event instead of keyup (as a user I think changing the text as I'm typing would be annoying to no end).

Generally, it's considered a bad practice to style standard form controls because the output looks so different on each browser. See: http://www.456bereastreet.com/lab/styling-form-controls-revisited/select-single/ for some rendered examples.

That being said, I've had some luck making the background color an RGBA value:

<!DOCTYPE html>
<html>
  <head>
    <style>
      body {
        background: #d00;
      }
      select {
        background: rgba(255,255,255,0.1) url('http://www.google.com/images/srpr/nav_logo6g.png') repeat-x 0 0; 
        padding:4px; 
        line-height: 21px;
        border: 1px solid #fff;
      }
    </style>
  </head>
  <body>
    <select>
      <option>Foo</option>
      <option>Bar</option>      
      <option>Something longer</option>     
  </body>
</html>

Google Chrome still renders a gradient on top of the background image in the color that you pass to rgba(r,g,b,0.1) but choosing a color that compliments your image and making the alpha 0.1 reduces the effect of this.

There are two ways to set this up. If you have an SID, use this (older) format:

jdbc:oracle:thin:@[HOST][:PORT]:SID

If you have an Oracle service name, use this (newer) format:

jdbc:oracle:thin:@//[HOST][:PORT]/SERVICE

Source: this OraFAQ page

The call to getConnection() is correct.

Also, as duffymo said, make sure the actual driver code is present by including ojdbc6.jar in the classpath, where the number corresponds to the Java version you're using.

You need to put that code into the constructor of your class:

private Reminders reminder = new Reminders();
private dynamic defaultReminder;

public YourClass()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
}

The reason is that you can't use one instance variable to initialize another one using a field initializer.

These are compact methods to encrypt / decrypt strings with PHP using AES256 CBC:

function encryptString($plaintext, $password, $encoding = null) {
    $iv = openssl_random_pseudo_bytes(16);
    $ciphertext = openssl_encrypt($plaintext, "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, $iv);
    $hmac = hash_hmac('sha256', $ciphertext.$iv, hash('sha256', $password, true), true);
    return $encoding == "hex" ? bin2hex($iv.$hmac.$ciphertext) : ($encoding == "base64" ? base64_encode($iv.$hmac.$ciphertext) : $iv.$hmac.$ciphertext);
}

function decryptString($ciphertext, $password, $encoding = null) {
    $ciphertext = $encoding == "hex" ? hex2bin($ciphertext) : ($encoding == "base64" ? base64_decode($ciphertext) : $ciphertext);
    if (!hash_equals(hash_hmac('sha256', substr($ciphertext, 48).substr($ciphertext, 0, 16), hash('sha256', $password, true), true), substr($ciphertext, 16, 32))) return null;
    return openssl_decrypt(substr($ciphertext, 48), "AES-256-CBC", hash('sha256', $password, true), OPENSSL_RAW_DATA, substr($ciphertext, 0, 16));
}

Usage:

$enc = encryptString("mysecretText", "myPassword");
$dec = decryptString($enc, "myPassword");

You can use:

  const sha1 = require('sha1');
  const crypt = sha1('Text');
  console.log(crypt);

For install:

  sudo npm install -g sha1
  npm install sha1 --save

It seems that there is in fact a pure CSS solution, requiring only the css attr expression, generated content and attribute selectors (which suggests that it works as far back as IE8):

https://jsfiddle.net/z42r2vv0/2/

a {
  position: relative;
  display: inline-block;
  margin-top: 20px;
}

a[title]:hover::after {
  content: attr(title);
  position: absolute;
  top: -100%;
  left: 0;
}

<a href="http://www.google.com/" title="Hello world!">
  Hover over me
</a>

update w/ input from @ViROscar: please note that it's not necessary to use any specific attribute, although I've used the "title" attribute in the example above; actually my recommendation would be to use the "alt" attribute, as there is some chance that the content will be accessible to users unable to benefit from CSS.

update again I'm not changing the code because the "title" attribute has basically come to mean the "tooltip" attribute, and it's probably not a good idea to hide important text inside a field only accessible on hover, but if you're interested in making this text accessible the "aria-label" attribute seems like the best place for it: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_aria-label_attribute

PORT 4369: Erlang makes use of a Port Mapper Daemon (epmd) for resolution of node names in a cluster. Nodes must be able to reach each other and the port mapper daemon for clustering to work.

There are several ways that you can transform data from multiple rows into columns.

Using PIVOT

In SQL Server you can use the PIVOT function to transform the data from rows to columns:

select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
  select value, columnname
  from yourtable
) d
pivot
(
  max(value)
  for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;

See Demo.

Pivot with unknown number of columnnames

If you have an unknown number of columnnames that you want to transpose, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT ',' + QUOTENAME(ColumnName) 
                    from yourtable
                    group by ColumnName, id
                    order by id
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = N'SELECT ' + @cols + N' from 
             (
                select value, ColumnName
                from yourtable
            ) x
            pivot 
            (
                max(value)
                for ColumnName in (' + @cols + N')
            ) p '

exec sp_executesql @query;

See Demo.

Using an aggregate function

If you do not want to use the PIVOT function, then you can use an aggregate function with a CASE expression:

select
  max(case when columnname = 'FirstName' then value end) Firstname,
  max(case when columnname = 'Amount' then value end) Amount,
  max(case when columnname = 'PostalCode' then value end) PostalCode,
  max(case when columnname = 'LastName' then value end) LastName,
  max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable

See Demo.

Using multiple joins

This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:

select fn.value as FirstName,
  a.value as Amount,
  pc.value as PostalCode,
  ln.value as LastName,
  an.value as AccountNumber
from yourtable fn
left join yourtable a
  on fn.somecol = a.somecol
  and a.columnname = 'Amount'
left join yourtable pc
  on fn.somecol = pc.somecol
  and pc.columnname = 'PostalCode'
left join yourtable ln
  on fn.somecol = ln.somecol
  and ln.columnname = 'LastName'
left join yourtable an
  on fn.somecol = an.somecol
  and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'

Yo can simply google for "exit sub in c#".

Also why would you check every text box if it is empty. You can place requiredfieldvalidator for these text boxes if this is an asp.net app and check if(Page.IsValid)

Or another solution is to get not of these conditions:

private void button1_Click(object sender, EventArgs e)
{
    if (!(textBox1.Text == "" || textBox2.Text == "" || textBox3.Text == ""))
    {
        //do events
    }
}

And better use String.IsNullOrEmpty:

private void button1_Click(object sender, EventArgs e)
{
    if (!(String.IsNullOrEmpty(textBox1.Text)
    || String.IsNullOrEmpty(textBox2.Text)
    || String.IsNullOrEmpty(textBox3.Text)))
    {
        //do events
    }
}

lookup = 'the dog barked'

with open(filename) as myFile:
    for num, line in enumerate(myFile, 1):
        if lookup in line:
            print 'found at line:', num

You can use float:left in DIV or use SPAN tag, like

<div style="width:100px;float:left"> First </div> 
<div> Second </div> 
<br/>

or

<span style="width:100px;"> First </span> 
<span> Second </span> 
<br/>

Convert the string to an InputStream and pass it to DocumentBuilder

final InputStream stream = new ByteArrayInputStream(string.getBytes(StandardCharsets.UTF_8));
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
builder.parse(stream);

EDIT
In response to bendin's comment regarding encoding, see shsteimer's answer to this question.

input[value=""], input:not([value])

works with:

<input type="text" />
<input type="text" value="" />

But the style will not change as soon as someone will start typing (you need JS for that).

If you only want to perform some specific operations by your second SP and do not require values back from the SP then simply do:

Exec secondSPName  @anyparams

Else, if you need values returned by your second SP inside your first one, then create a temporary table variable with equal numbers of columns and with same definition of column return by second SP. Then you can get these values in first SP as:

Insert into @tep_table
Exec secondSPName @anyparams

Update:

To pass parameter to second sp, do this:

Declare @id ID_Column_datatype 
Set @id=(Select id from table_1 Where yourconditions)

Exec secondSPName @id

Update 2:

Suppose your second sp returns Id and Name where type of id is int and name is of varchar(64) type.

now, if you want to select these values in first sp then create a temporary table variable and insert values into it:

Declare @tep_table table
(
  Id int,
  Name varchar(64)
)
Insert into @tep_table
Exec secondSP

Select * From @tep_table

This will return you the values returned by second SP.

Hope, this clear all your doubts.

This should actually do what the OP specifies:

One-liner in Bash:

$ for first_level in `find . -maxdepth 1 -type d`; do find $first_level -printf "%TY-%Tm-%Td %TH:%TM:%TS $first_level\n" | sort -n | tail -n1 ; done

which gives output such as:

2020-09-12 10:50:43.9881728000 .
2020-08-23 14:47:55.3828912000 ./.cache
2018-10-18 10:48:57.5483235000 ./.config
2019-09-20 16:46:38.0803415000 ./.emacs.d
2020-08-23 14:48:19.6171696000 ./.local
2020-08-23 14:24:17.9773605000 ./.nano

This lists each first-level directory with the human-readable timestamp of the latest file within those folders, even if it is in a subfolder, as requested in

"I need to make a list of all these directories that is constructed in a way such that every first-level directory is listed next to the date and time of the latest created/modified file within it."

In your case you would use two case staements, one for each value you want returned.

What you want is this (actually the exact inverse of the currently accepted answer):

git checkout email
git merge --strategy-option=theirs staging  

What this does is:

• email branch files will now be exactly the same as staging branch
• email branch's history will be maintained
• staging branch's history will be added to email history

As added value, if you don't want all of staging branch's history, you can use squash to summarize it into a single commit message.

git checkout email
git merge --squash --strategy-option=theirs staging  
git commit -m "Single commit message for squash branch's history here'

So in summary, what this second version does is:

• email branch files will now be exactly the same as staging branch
• email branch's history will be maintained
• A single commit will be added on top of email branch's history. This commit will represent ALL the changes that took place in the staging branch

Try using dynamic SQL:

create procedure sp_First @columnname varchar 
AS 
begin 
    declare @sql nvarchar(4000);
    set @sql='select ['+@columnname+'] from Table_1';
    exec sp_executesql @sql
end 
go

exec sp_First 'sname'
go

I've tried several minifiers and they either remove too little or too much.

This code removes redundant empty spaces and optional HTML (ending) tags. Also it plays it safe and does not remove anything that could potentially break HTML, JS or CSS.

Also the code shows how to do that in Zend Framework:

class Application_Plugin_Minify extends Zend_Controller_Plugin_Abstract {

  public function dispatchLoopShutdown() {
    $response = $this->getResponse();
    $body = $response->getBody(); //actually returns both HEAD and BODY

    //remove redundant (white-space) characters
    $replace = array(
        //remove tabs before and after HTML tags
        '/\>[^\S ]+/s'   => '>',
        '/[^\S ]+\</s'   => '<',
        //shorten multiple whitespace sequences; keep new-line characters because they matter in JS!!!
        '/([\t ])+/s'  => ' ',
        //remove leading and trailing spaces
        '/^([\t ])+/m' => '',
        '/([\t ])+$/m' => '',
        // remove JS line comments (simple only); do NOT remove lines containing URL (e.g. 'src="http://server.com/"')!!!
        '~//[a-zA-Z0-9 ]+$~m' => '',
        //remove empty lines (sequence of line-end and white-space characters)
        '/[\r\n]+([\t ]?[\r\n]+)+/s'  => "\n",
        //remove empty lines (between HTML tags); cannot remove just any line-end characters because in inline JS they can matter!
        '/\>[\r\n\t ]+\</s'    => '><',
        //remove "empty" lines containing only JS's block end character; join with next line (e.g. "}\n}\n</script>" --> "}}</script>"
        '/}[\r\n\t ]+/s'  => '}',
        '/}[\r\n\t ]+,[\r\n\t ]+/s'  => '},',
        //remove new-line after JS's function or condition start; join with next line
        '/\)[\r\n\t ]?{[\r\n\t ]+/s'  => '){',
        '/,[\r\n\t ]?{[\r\n\t ]+/s'  => ',{',
        //remove new-line after JS's line end (only most obvious and safe cases)
        '/\),[\r\n\t ]+/s'  => '),',
        //remove quotes from HTML attributes that does not contain spaces; keep quotes around URLs!
        '~([\r\n\t ])?([a-zA-Z0-9]+)="([a-zA-Z0-9_/\\-]+)"([\r\n\t ])?~s' => '$1$2=$3$4', //$1 and $4 insert first white-space character found before/after attribute
    );
    $body = preg_replace(array_keys($replace), array_values($replace), $body);

    //remove optional ending tags (see http://www.w3.org/TR/html5/syntax.html#syntax-tag-omission )
    $remove = array(
        '</option>', '</li>', '</dt>', '</dd>', '</tr>', '</th>', '</td>'
    );
    $body = str_ireplace($remove, '', $body);

    $response->setBody($body);
  }
}

But note that when using gZip compression your code gets compressed a lot more that any minification can do so combining minification and gZip is pointless, because time saved by downloading is lost by minification and also saves minimum.

Here are my results (download via 3G network):

 Original HTML:        150kB       180ms download
 gZipped HTML:          24kB        40ms
 minified HTML:        120kB       150ms download + 150ms minification
 min+gzip HTML:         22kB        30ms download + 150ms minification

The shortest I got: b = a[:2] + [3] + a[2:]

>>>
>>> a = [1, 2, 4]
>>> print a
[1, 2, 4]
>>> b = a[:2] + [3] + a[2:]
>>> print a
[1, 2, 4]
>>> print b
[1, 2, 3, 4]

Simply, GoogleAdMobAds.a is missing in project target. For me it was libAdIdAccessLibrary.a Please check attached screenshot

It turns out that because of a peculiar mixture of javascript frameworks that I needed to initiate the script using an event listener provide by one of the other frameworks.

It improves readability of your code, provides extra type safety and save some compiler efforts.

Say you want to print each element of a container, you can use the following code without template template parameter

template <typename T> void print_container(const T& c)
{
    for (const auto& v : c)
    {
        std::cout << v << ' ';
    }
    std::cout << '\n';
}

or with template template parameter

template< template<typename, typename> class ContainerType, typename ValueType, typename AllocType>
void print_container(const ContainerType<ValueType, AllocType>& c)
{
    for (const auto& v : c)
    {
        std::cout << v << ' ';
    }
    std::cout << '\n';
}

Assume you pass in an integer say print_container(3). For the former case, the template will be instantiated by the compiler which will complain about the usage of c in the for loop, the latter will not instantiate the template at all as no matching type can be found.

Generally speaking, if your template class/function is designed to handle template class as template parameter, it is better to make it clear.

The check can be made easier with diff:

diff <(ssh-keygen -y -f $private_key_file) $public_key_file

The only odd thing is that diff says nothing if the files are the same, so you'll only be told if the public and private don't match.

sounds like you downloaded the german xampp package instead of the english xampp package (yes, it's another download-link) where the language is set according to the package you loaded. to change the language afterwards, simply edit the config.inc.php and set:

$cfg['Lang'] = 'en-utf-8';

If your emulator x86 this method works your me.

Notice that if the file's parent folder doesn't exist you'll get the same error:

IOError: [Errno 2] No such file or directory:

Below is another solution which handles this case:
(*) I used sys.stdout and print instead of f.write just to show another use case

# Make sure the file's folder exist - Create folder if doesn't exist
folder_path = 'path/to/'+folder_name+'/'
if not os.path.exists(folder_path):
     os.makedirs(folder_path)

print_to_log_file(folder_path, "Some File" ,"Some Content")

Where the internal print_to_log_file just take care of the file level:

# If you're not familiar with sys.stdout - just ignore it below (just a use case example)
def print_to_log_file(folder_path ,file_name ,content_to_write):

   #1) Save a reference to the original standard output       
    original_stdout = sys.stdout   
    
    #2) Choose the mode
    write_append_mode = 'a' #Append mode
    file_path = folder_path + file_name
    if (if not os.path.exists(file_path) ):
       write_append_mode = 'w' # Write mode
     
    #3) Perform action on file
    with open(file_path, write_append_mode) as f:
        sys.stdout = f  # Change the standard output to the file we created.
        print(file_path, content_to_write)
        sys.stdout = original_stdout  # Reset the standard output to its original value

Consider the following states:

'w'  --> Write to existing file
'w+' --> Write to file, Create it if doesn't exist
'a'  --> Append to file
'a+' --> Append to file, Create it if doesn't exist

In your case I would use a different approach and just use 'a' and 'a+'.

The blocksize is usually selected to maximize the "occupancy". Search on CUDA Occupancy for more information. In particular, see the CUDA Occupancy Calculator spreadsheet.

SafeAreaLayoutGuide is UIView property,

The top of the safeAreaLayoutGuide indicates the unobscured top edge of the view (e.g, not behind the status bar or navigation bar, if present). Similarly for the other edges.

Use safeAreaLayoutGuide for avoid our objects clipping/overlapping from rounded corners, navigation bars, tab bars, toolbars, and other ancestor views.

We can create safeAreaLayoutGuide object & set object constraints respectively.

Constraints for Portrait + Landscape is -

        self.edgesForExtendedLayout = []//Optional our as per your view ladder

        let newView = UIView()
        newView.backgroundColor = .red
        self.view.addSubview(newView)
        newView.translatesAutoresizingMaskIntoConstraints = false
        if #available(iOS 11.0, *) {
            let guide = self.view.safeAreaLayoutGuide
            newView.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
            newView.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
            newView.topAnchor.constraint(equalTo: guide.topAnchor).isActive = true
            newView.heightAnchor.constraint(equalToConstant: 100).isActive = true

        }
        else {
            NSLayoutConstraint(item: newView, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: newView, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: newView, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1.0, constant: 0).isActive = true

            newView.heightAnchor.constraint(equalToConstant: 100).isActive = true

Have you tried layerGroup yet?

Docs here https://leafletjs.com/reference-1.2.0.html#layergroup

Just create a layer, add all marker to this layer, then you can find and destroy marker easily.

var markers = L.layerGroup()
const marker = L.marker([], {})
markers.addLayer(marker)

You could do this, where td is your series of timedeltas. The division converts the nanosecond deltas into day deltas, and the conversion to int drops to whole days.

import numpy as np

(td / np.timedelta64(1, 'D')).astype(int)

Arrays must have zero based integer indexes in JavaScript. So:

var valueToPush = new Array();
valueToPush[0] = productID;
valueToPush[1] = itemColorTitle;
valueToPush[2] = itemColorPath;
cookie_value_add.push(valueToPush);

Or maybe you want to use objects (which are associative arrays):

var valueToPush = { }; // or "var valueToPush = new Object();" which is the same
valueToPush["productID"] = productID;
valueToPush["itemColorTitle"] = itemColorTitle;
valueToPush["itemColorPath"] = itemColorPath;
cookie_value_add.push(valueToPush);

which is equivalent to:

var valueToPush = { };
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;
cookie_value_add.push(valueToPush);

It's a really fundamental and crucial difference between JavaScript arrays and JavaScript objects (which are associative arrays) that every JavaScript developer must understand.

You have to specify that test1 is global:

test1 = 0
def testFunc():
    global test1
    test1 += 1
testFunc()

You can add files using git add, example git add README, git add <folder>/*, or even git add *

Then use git commit -m "<Message>" to commit files

Finally git push -u origin master to push files.

When you make modifications run git status which gives you the list of files modified, add them using git add * for everything or you can specify each file individually, then git commit -m <message> and finally, git push -u origin master

Example - say you created a file README, running git status gives you

$ git status
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   README

Run git add README, the files are staged for committing. Then run git status again, it should give you - the files have been added and ready for committing.

$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   new file:   README
#

nothing added to commit but untracked files present (use "git add" to track)

Then run git commit -m 'Added README'

$ git commit -m 'Added README'
[master 6402a2e] Added README
  0 files changed, 0 insertions(+), 0 deletions(-)
  create mode 100644 README

Finally, git push -u origin master to push the remote branch master for the repository origin.

My answer below shows how to embed images using data URIs. This is useful for the web, but will not work reliably for most email clients. For email purposes be sure to read Shadow2531's answer.

Base-64 data is legal in an img tag and I believe your question is how to properly insert such an image tag.

You can use an online tool or a few lines of code to generate the base 64 string.

The syntax to source the image from inline data is:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

slapcat > backup.ldif

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

Since I just ran in to this problem on a shared host and was unable to add the values to my .htaccess file I thought I'd share my solution.

I made an ini file with the values in it. Simple as that:

Make a file called ".user.ini" and add your values

upload_max_filesize = 150M
post_max_size = 150M

Boom, problem solved.

Since this is tagged C# 4. With the open sourece framework ImpromptuIntereface it will use the dlr to call the constructor it is significantly faster than Activator when your constructor has arguments, and negligibly slower when it doesn't. However the main advantage is that it will handle constructors with C# 4.0 optional parameters correctly, something that Activator won't do.

protected T GetObject(params object[] args)
{
    return (T)Impromptu.InvokeConstructor(typeof(T), args);
}

You can use primefaces library

How about:

>>> string_2 = "(555) 555 - 5555 ext. 5555"
>>> any(c.isalpha() for c in string_1)
False
>>> any(c.isalpha() for c in string_2)
True

use coalesce

COALESCE(value [, ...])

The COALESCE function returns the first of its arguments that is not null.  
Null is returned only if all arguments are null. It is often
used to substitute a default value for null values when data is
retrieved for display.

Edit

Here's an example of COALESCE with your query:

SELECT AVG( price )
FROM(
      SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
      WHERE listing_Type = 'AARM'
        AND u_kbalikepartnumbers_id = 1000307
        AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
        AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
                                     FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48

                                    WHERE cume_dist < 0.50
                                  )
        AND COALESCE( price, 0 ) < ( SELECT AVG( COALESCE( price, 0 ) ) *2
                                     FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48

                                     WHERE cume_dist < 0.50)
     )s
HAVING COUNT(*) > 5

IMHO COALESCE should not be use with AVG because it modifies the value. NULL means unknown and nothing else. It's not like using it in SUM. In this example, if we replace AVG by SUM, the result is not distorted. Adding 0 to a sum doesn't hurt anyone but calculating an average with 0 for the unknown values, you don't get the real average.

In that case, I would add price IS NOT NULL in WHERE clause to avoid these unknown values.

You need to store the psftp script (lines from open to bye) into a separate file and pass that to psftp using -b switch:

cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b

EDIT: For username+password: As you cannot use psftp commands in a batch file, for the same reason, you cannot specify the username and the password as psftp commands. These are inputs to the open command. While you can specify the username with the open command (open <user>@<IP>), you cannot specify the password this way. This can be done on a psftp command line only. Then it's probably cleaner to do all on the command-line:

cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>

And remove the open, <user> and <PW> lines from your script.txt.

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw

What you are doing atm is that you run psftp without any parameter or commands. Once you exit it (like by typing bye), your batch file continues trying to run open command (and others), what Windows shell obviously does not understand.

If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:

(
    echo cd ...
    echo lcd ...
    echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

The simplest way is to:

1. intercept every button state

2. add !important to override the states

    .btn-primary:hover,
    .btn-primary:active,
    .btn-primary:visited,
    .btn-primary:focus {
      background-color: black !important;
      border-color: black !important;
    }

OR the more practical UI way is to make the hover state of the button darker than the original state. Just use the CSS snippet below:

.btn-primary {
  background-color: Blue !important;
  border-color: Blue !important;
}
.btn-primary:hover,
.btn-primary:active,
.btn-primary:visited,
.btn-primary:focus {
  background-color: DarkBlue !important;
  border-color: DarkBlue !important;
}

(PartlyStolen from ServerFault)

I think that both are functionally the same, but they simply have different authors, and the one is simply named more appropriately than the other.

Here is a quick backgrounder in naming conventions (for those unfamiliar), which explains the frustration by the question asker: For many *nix applications, the piece that does the backend work is called a "daemon" (think "service" in Windows-land), while the interface or client application is what you use to control or access the daemon. The daemon is most often named the same as the client, with the letter "d" appended to it. For example "imap" would be a client that connects to the "imapd" daemon.

This naming convention is clearly being adhered to by memcache when you read the introduction to the memcache module (notice the distinction between memcache and memcached in this excerpt):

Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications.

The Memcache module also provides a session handler (memcache).

More information about memcached can be found at » http://www.danga.com/memcached/.

The frustration here is caused by the author of the PHP extension which was badly named memcached, since it shares the same name as the actual daemon called memcached. Notice also that in the introduction to memcached (the php module), it makes mention of libmemcached, which is the shared library (or API) that is used by the module to access the memcached daemon:

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

This extension uses libmemcached library to provide API for communicating with memcached servers. It also provides a session handler (memcached).

Information about libmemcached can be found at » http://tangent.org/552/libmemcached.html.

The way I do it is the following (better than type assertion imho):

onFieldUpdate(event: { target: HTMLInputElement }) {
  this.$emit('onFieldUpdate', event.target.value);
}

This assumes you are only interested in the target property, which is the most common case. If you need to access the other properties of event, a more comprehensive solution involves using the & type intersection operator:

event: Event & { target: HTMLInputElement }

This is a Vue.js version but the concept applies to all frameworks. Obviously you can go more specific and instead of using a general HTMLInputElement you can use e.g. HTMLTextAreaElement for textareas.

You can try this click event

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex >= 0)
    {
        DataGridViewRow row = this.dataGridView1.Rows[e.RowIndex];
        Eid_txt.Text = row.Cells["Employee ID"].Value.ToString();
        Name_txt.Text = row.Cells["First Name"].Value.ToString();
        Surname_txt.Text = row.Cells["Last Name"].Value.ToString();

If you want to catch Exception for each iteration, or check at what iteration Exception is thrown and catch every Exceptions in an itertaion, place try...catch inside the loop. This will not break the loop if Exception occurs and you can catch every Exception in each iteration throughout the loop.

If you want to break the loop and examine the Exception whenever thrown, use try...catch out of the loop. This will break the loop and execute statements after catch (if any).

It all depends on your need. I prefer using try...catch inside the loop while deploying as, if Exception occurs, the results aren't ambiguous and loop will not break and execute completely.

tl;dr: baz() { this.foo(); this.bar() }

In ES2015 this construct:

var obj = {
    foo() { console.log('foo') }
}

is equal to this ES5 code:

var obj = {
    foo : function foo() { console.log('foo') }
}

exports.default = {} is like creating an object, your default export translates to ES5 code like this:

exports['default'] = {
    foo: function foo() {
        console.log('foo');
    },
    bar: function bar() {
        console.log('bar');
    },
    baz: function baz() {
        foo();bar();
    }
};

now it's kind of obvious (I hope) that baz tries to call foo and bar defined somewhere in the outer scope, which are undefined. But this.foo and this.bar will resolve to the keys defined in exports['default'] object. So the default export referencing its own methods shold look like this:

export default {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { this.foo(); this.bar() }
}

See babel repl transpiled code.

It's valid in C for historical reasons. C traditionally specified that the type of a string literal was char * rather than const char *, although it qualified it by saying that you're not actually allowed to modify it.

When you use a cast, you're essentially telling the compiler that you know better than the default type matching rules, and it makes the assignment OK.

• validate: validates the schema, no change happens to the database.
• update: updates the schema with current execute query.
• create: creates new schema every time, and destroys previous data.
• create-drop: drops the schema when the application is stopped or SessionFactory is closed explicitly.

You can use readAllBytes.

return String(Files.readAllBytes(Paths.get(filePath)),StandardCharsets.UTF_8);

for Python in Windows:

python -m pip uninstall "package_keyword"
uninstall **** (y/n)?

Going through the answers there are some details missing regarding `Cascade' and id generation. See question

Also, it is worth mentioning that you can have separate Cascade annotations for merging and persisting: Cascade.MERGE and Cascade.PERSIST which will be treated according to the used method.

The spec is your friend ;)

int index = dt.Rows.IndexOf(row);

But you're probably better off using a for loop instead of foreach.

It's a table-valued function, but you're using it as a scalar function.

Try:

where Emp_Id IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)

But... also consider changing your function into an inline TVF, as it'll perform better.

Use a cast:

public enum MyEnum : int    {
    A = 0,
    B = 1,
    AB = 2,
}


int val = (int)MyEnum.A;

The entire story begins with a feature of swift called optional vars. These are the vars which may have a value or may not have a value. In general swift doesn't allow us to use a variable which isn't initialised, as this may lead to crashes or unexpected reasons and also server a placeholder for backdoors. Thus in order to declare a variable whose value isn't initially determined we use a '?'. When such a variable is declared, to use it as a part of some expression one has to unwrap them before use, unwrapping is an operation through which value of a variable is discovered this applies to objects. Without unwrapping if you try to use them you will have compile time error. To unwrap a variable which is an optional var, exclamation mark "!" is used.

Now there are times when you know that such optional variables will be assigned values by system for example or your own program but sometime later , for example UI outlets, in such situation instead of declaring an optional variable using a question mark "?" we use "!".

Thus system knows that this variable which is declared with "!" is optional right now and has no value but will receive a value in later in its lifetime.

Thus exclamation mark holds two different usages, 1. To declare a variable which will be optional and will receive value definitely later 2. To unwrap an optional variable before using it in an expression.

Above descriptions avoids too much of technical stuff, i hope.

As other people suggested, you need to use a combobox. However, most tutorials show you how to set up just one combobox and the process is quite tedious.

As I faced this problem before when entering a large amount of data from a list, I can suggest you use this autocomplete add-in . It helps you create the combobox on any cells you select and you can define a list to appear in the dropdown.

What is a constant reference (not a reference to a constant)
A Constant Reference is actually a Reference to a Constant.

A constant reference/ Reference to a constant is denoted by:

int const &i = j; //or Alternatively
const int &i = j;
i = 1;            //Compilation Error

It basically means, you cannot modify the value of type object to which the Reference Refers.
For Example:
Trying to modify value(assign 1) of variable j through const reference, i will results in error:

assignment of read-only reference ‘i’

icr=y;          // Can change the object it is pointing to so it's not like a const pointer...
icr=99;

Doesn't change the reference, it assigns the value of the type to which the reference refers. References cannot be made to refer any other variable than the one they are bound to at Initialization.

First statement assigns the value y to i
Second statement assigns the value 99 to i

Try the following code:

    Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
    config.AppSettings.Settings.Add("YourKey", "YourValue");
    config.Save(ConfigurationSaveMode.Minimal);

It worked for me :-)

Just assign row to a particular index, using loc:

 df.loc[-1] = [2, 3, 4]  # adding a row
 df.index = df.index + 1  # shifting index
 df = df.sort_index()  # sorting by index

And you get, as desired:

    A  B  C
 0  2  3  4
 1  5  6  7
 2  7  8  9

If I talked about my scenario here, non of above answers will not worked because I had activity that show list of db values along with a delete button and when a delete button is pressed, I wanted to delete that item from the list.

The cool thing was, I did not used recycler view but a simple list view and that list view initialized in the adapter class. So, calling the notifyDataSetChanged() will not do anything inside the adapter class and even in the activity class where adapter object is initialized because delete method was in the adapter class.

So, the solution was to remove the object from the adapter in the adapter class getView method(to only delete that specific object but if you want to delete all, call clear()).

To you to get some idea, what was my code look like,

public class WordAdapter extends ArrayAdapter<Word> {
  Context context;

  public WordAdapter(Activity context, ArrayList<Word> words) {}
    //.......

    @NonNull
    @Override
    public View getView(final int position, View convertView, ViewGroup group) {
      //.......
     ImageButton deleteBt = listItemView.findViewById(R.id.word_delete_bt);
     deleteBt.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
             if (vocabDb.deleteWord(currentWord.id)) {
                //.....
             } else{
                //.....
             }
             remove(getItem(position)); // <---- here is the trick ---<
             //clear() // if you want to clear everything
         }
    });
 //....

Note: here remove() and getItem() methods are inherit from the Adapter class.

• remove() - to remove the specific item that is clicked
• getItem(position) - is to get the item(here, thats my Word object that I have added to the list) from the clicked position.

This is how I set the adapter to the listview in the activity class,

    ArrayList<Word> wordList = new ArrayList();
    WordAdapter adapter = new WordAdapter(this, wordList);

    ListView list_view = (ListView) findViewById(R.id.activity_view_words);
    list_view.setAdapter(adapter);

There is a difference in the * usage when you are defining a variable and when you are using it.

In declaration,

int *myVariable;

Means a pointer to an integer data type. In usage however,

*myVariable = 3;

Means dereference the pointer and make the structure it is pointing at equal to three, rather then make the pointer equal to the memory address 0x 0003.

So in your function, you want to do this:

void makePointerEqualSomething(int* pInteger)
{
    *pInteger = 7;
}

In the function declaration, * means you are passing a pointer, but in its actual code body * means you are accessing what the pointer is pointing at.

In an attempt to wave away any confusion you have, I'll briefly go into the ampersand (&)

& means get the address of something, its exact location in the computers memory, so

 int & myVariable;

In a declaration means the address of an integer, or a pointer!

This however

int someData;    
pInteger = &someData;

Means make the pInteger pointer itself (remember, pointers are just memory addresses of what they point at) equal to the address of 'someData' - so now pInteger will point at some data, and can be used to access it when you deference it:

*pInteger += 9000;

Does this make sense to you? Is there anything else that you find confusing?

@Edit3:

Nearly correct, except for three statements

bar = *oof;

means that the bar pointer is equal to an integer, not what bar points at, which is invalid.

&bar = &oof;

The ampersand is like a function, once it returns a memory address you cannot modify where it came from. Just like this code:

returnThisInt("72") = 86; 

Is invalid, so is yours.

Finally,

bar = oof

Does not mean that "bar points to the oof pointer." Rather, this means that bar points to the address that oof points to, so bar points to whatever foo is pointing at - not bar points to foo which points to oof.

In case this is of interest to anyone, I had the same problem when I was running Python in Cygwin, in my case it was complaning that pandas wasn't installed even though it was. The problem was that I had 2 installations of python - one in windows and another one in cygwin (using the cygwin installer) and although both were the same versions of Python, the Cygwin installation was confused about where Pandas was installed. When i uninstalled cygwin's Python and pointed Cygwin at the windows installation everything was fine

The ConcurrentHashMap is very similar to the HashMap class, except that ConcurrentHashMap offers internally maintained concurrency. It means you do not need to have synchronized blocks when accessing ConcurrentHashMap in multithreaded application.

To get all key-value pairs in ConcurrentHashMap, below code which is similar to your code works perfectly:

//Initialize ConcurrentHashMap instance
ConcurrentHashMap<String, Integer> m = new ConcurrentHashMap<String, Integer>();

//Print all values stored in ConcurrentHashMap instance
for each (Entry<String, Integer> e : m.entrySet()) {
  System.out.println(e.getKey()+"="+e.getValue());
}

Above code is reasonably valid in multi-threaded environment in your application. The reason, I am saying 'reasonably valid' is that, above code yet provides thread safety, still it can decrease the performance of application.

Hope this helps you.

This is what helped me:

1. Create a new branch with the existing one. Let's call the existing one branch_old and new as branch_new.

2. Reset branch_new to a stable state, when you did not have any problem commit at all. For example, to put it at your local master's level do the following:

   git reset —hard master git push —force origin

3. cherry-pick the commits from branch_old into branch_new

4. git push

I use the npm clone library. Apparently it also works in the browser.

https://www.npmjs.com/package/clone

let a = clone(b)

This might be of interest:

function isElement(obj) {
  try {
    //Using W3 DOM2 (works for FF, Opera and Chrome)
    return obj instanceof HTMLElement;
  }
  catch(e){
    //Browsers not supporting W3 DOM2 don't have HTMLElement and
    //an exception is thrown and we end up here. Testing some
    //properties that all elements have (works on IE7)
    return (typeof obj==="object") &&
      (obj.nodeType===1) && (typeof obj.style === "object") &&
      (typeof obj.ownerDocument ==="object");
  }
}

It's part of the DOM, Level2.

Update 2: This is how I implemented it in my own library: (the previous code didn't work in Chrome, because Node and HTMLElement are functions instead of the expected object. This code is tested in FF3, IE7, Chrome 1 and Opera 9).

//Returns true if it is a DOM node
function isNode(o){
  return (
    typeof Node === "object" ? o instanceof Node : 
    o && typeof o === "object" && typeof o.nodeType === "number" && typeof o.nodeName==="string"
  );
}

//Returns true if it is a DOM element    
function isElement(o){
  return (
    typeof HTMLElement === "object" ? o instanceof HTMLElement : //DOM2
    o && typeof o === "object" && o !== null && o.nodeType === 1 && typeof o.nodeName==="string"
);
}

add JAVA_HOME to the file:

/etc/environment

for it to be available to the entire system (you would need to restart Ubuntu though)

The very concept of a "proper" way to do anything, apart from using CPAN, is non existent in Perl.

Anyways those are numeric operators, you should use

if($foo eq "")

or

if(length($foo) == 0)

Since I18n is the Rails core feature starting from version 2.2 you can use its localize-method. By applying the forementioned strftime %-variables you can specify the desired format under config/locales/en.yml (or whatever language), in your case like this:

time:
  formats:
    default: '%FT%T'

Or if you want to use this kind of format in a few specific places you can refer it as a variable like this

time:
  formats:
    specific_format: '%FT%T'

After that you can use it in your views like this:

l(Mode.last.created_at, format: :specific_format)  

If you like GUI and are using Windows, here is an easy way.

1. Download WinMerge
2. Check out the two branches into different folders
3. Do a folder by folder compare using WinMerge. You can also easily make modifications if one of the branches is the one you are working on.

Think of it as Java's answer to the PATH environment variable - OSes search for EXEs on the PATH, Java searches for classes and packages on the classpath.

I've got the same error with android-maps-utils dependency. Using aar type package in dependency section solve my problem. By default type is jar so It might be checked what type of dependency in repository is downloaded.

You want to set style

I know this will center horrizontaly but I'm not sure about vertical!

The complete article that works for me: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding

The part where we encode from Unicode/UTF-8 is

function utf8_to_b64( str ) {
   return window.btoa(unescape(encodeURIComponent( str )));
}

function b64_to_utf8( str ) {
   return decodeURIComponent(escape(window.atob( str )));
}

// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

This is one of the most used methods nowadays.

For people who prefer the JavaScript solution. In Bootstrap 4 tip() became getTipElement() and it returns a no jQuery object. So in order to change the width of the popover in Bootstrap 4 you can use:

}).on("show.bs.popover", function() {
    $($(this).data("bs.popover").getTipElement()).css("max-width", "405px");
});

Two things. First, you need to qualify the enum reference in your test - rather than "PLUS", it should be "Operator.PLUS". Second, this code would be a lot more readable if you used the enum member names rather than their integral values in the switch statement. I've updated your code:

public enum Operator
{
    PLUS, MINUS, MULTIPLY, DIVIDE
}

public static double Calculate(int left, int right, Operator op)
{
    switch (op)
    {
        default:
        case Operator.PLUS:
            return left + right;

        case Operator.MINUS:
            return left - right;

        case Operator.MULTIPLY:
            return left * right;

        case Operator.DIVIDE:
            return left / right;
    }
}

Call this with:

Console.WriteLine("The sum of 5 and 5 is " + Calculate(5, 5, Operator.PLUS));

precision: Its the total number of digits before or after the radix point. EX: 123.456 here precision is 6.

Scale: Its the total number of digits after the radix point. EX: 123.456 here Scaleis 3

This works for me

while (document.getElementsByClassName('my-class')[0]) {
        document.getElementsByClassName('my-class')[0].remove();
    }

The error "Message: element not interactable" mostly occurs when your element is not clickable or it is not visible yet, and you should click or choose one other element before it. Then your element will get displayed and you can modify it.

You can check if your element is visible or not by calling is_displayed() method like this:

print("Element is visible? " + str(element_name.is_displayed()))

As noted in the answer provided by Tim Cooper, java.awt.Desktop has provided this capability since Java version 6 (1.6), but with the following caveat:

Use the isDesktopSupported() method to determine whether the Desktop API is available. On the Solaris Operating System and the Linux platform, this API is dependent on Gnome libraries. If those libraries are unavailable, this method will return false.

For platforms which do not support or provide java.awt.Desktop, look into the BrowserLauncher2 project. It is derived and somewhat updated from the BrowserLauncher class originally written and released by Eric Albert. I used the original BrowserLauncher class successfully in a multi-platform Java application which ran locally with a web browser interface in the early 2000s.

Note that BrowserLauncher2 is licensed under the GNU Lesser General Public License. If that license is unacceptable, look for a copy of the original BrowserLauncher which has a very liberal license:

Projects other than BrowserLauncher2 may have also updated the original BrowserLauncher to account for changes in browser and default system security settings since 2001.

I solved it this way:

Call the following just before calling your ssl webservice that cause that error:

using System.Net;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;

/// <summary>
/// solution for exception
/// System.Net.WebException: 
/// The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
/// </summary>
public static void BypassCertificateError()
{
    ServicePointManager.ServerCertificateValidationCallback +=

        delegate(
            Object sender1,
            X509Certificate certificate,
            X509Chain chain,
            SslPolicyErrors sslPolicyErrors)
        {
            return true;
        };
}

There is no => for if.
Use if %energy% GEQ %m2enc%

See if /? for some other details.
